从 2 个模式获取 CSV 并忽略所有其余内容

Question

有一种模式，它的开头相同，但结尾略有不同，一个模式从开头继续，然后我想保留该行剩余部分，另一个模式我想立即保留，但在该行结束之前我想忽略一些东西，两者之间也有一些我想忽略的内容。

在以下示例中，我想制作一个甜点†的 CSV 文件，其中蔬菜是图案，lorem ipsum 是中间的线条。我想用 Notepad++ 来做这件事。到目前为止，我已经.*?carrot\Rpotato (?:cabbage (.*?)|(.*?) turnip)\R.*?用 替换了\1,，但这似乎不起作用；我还怀疑这不是获得我想要的东西的最有效方法。

非常感谢你

Answer 1

• Ctrl+H
• 找什么：.*?carrot\Rpotato (?|cabbage ((?:(?!turnip).)*)\R?|((?:(?!cabbage).)*) turnip).*\R?|.+\R?
• 用。。。来代替：(?1$1,)
• 打钩 相符
• 打钩 环绕
• 选择 正则表达式
• 取消勾选 . matches newline
• Replace all

解释：

.*?             # 0 or more any character but newline, not greedy
carrot          # literally
\R              # any kind of linebreak
potato          # literally
(?|             # branch reset groups
    cabbage         # literally
    (               # group 1
        # tempered greedy token
        (?:             # non capture group
            (?!turnip)      # negative lookahead, make sure we haven't turnip after
            .               # any character but newline
        )*              # end group, may appear 0 or more times
    )               # end group 1
    \R?             # optional linebreak
  |               # OR
    (               # group 1 (same group number as above because of the directive "branch reset groups")
        # tempered greedy token
        (?:             # non capture group
            (?!cabbage)     # negative lookahead, make sure we haven't cabbage after
            .               # any character but newline
        )*              # end group, may appear 0 or more times
    )               # end group 1
     turnip         # literally
)               # end branch reset groups
    .*\R?           # 0 or more any character followed by optional linebreak
|               # OR
    .+\R?           # 1 or more any character followed by optional linebreak

替代品：

(?1         # if group 1 exists
    $1,         # print the content of group 1 followed by a comma
)           # end if
